2009-2010赛季CSL技战术空间结构研究

The Spatial Structure of CSL Tactics in 2009,2010 Season

以GSL2009、2010两个赛季各参赛队为研究对象,每赛季240场次共480场次为研究载体,选取9项具有统计意义及实践意义的代表性指标,对两个赛季中超技战术状况进行初步的描述性分析,了解其差异性及共性。在此基础上,运用降维理论,采用因子分析法,提取每个赛季的5个共性因子,解释其内容,且对其因子结构进行统计分析(t检验)。统计结果表明:20092、010两个赛季初级指标分析中,发生变化的指标为:失球数、控球率、攻入前场30 m数三项初始指标,尤其是失球数、攻入前场30 m数两项初级指标P(sig=0.002)<0.01,P(sig=0.007)<0.01,差异性显著;两个赛季因子结构变化较小,因子结构变化主要体现在失球数的归属,因子结构总体差异性不明显(sig>0.05);该数据结果及空间结构分析对我国足球技战术训练水平的提高有很好的参考意义,对我国"净化"足球文化,提高联赛公平竞赛的质量和水平有极好的实践意义,具有一定的可操作性。

In 2009,2010 two seasons every team as the re^mreh object, each season 240 sequences,480 streak for research carrier, choose 9 statistical signifi- cance and practical significance of representative indexes, the two seasons on - linechelation technical - tactical status carries on the preliminary descriptive analysis, understand their differences and similarities, on this basis, using redueed- order theories, using factor analysis, extraction each season five commou factor, explaining its content, and commits any substructure of statistical analysis （t test）. Statistical results show that 2009,2010 two seasons primary index analysis, change index for： clean sheet number, ball possession, scoring froutcourt 30 lneters number three initial indicator, especially clean sheet number, scoring frentcourt 30 meters number two primary index （ P = 0.002 ） sig 〈 0.01, P = 0.007） （ sig 〈 0.01, differences remarkable; Two seasons factor struc- ture changes smaller factor structure change are mainly embodied in the ownership of the clean sheet number, overall difference is not obvious factor structure （ sig 〉 0.05）. This data results and spatial structure analysis to our country fcotball tactics to raise the level of a very good reference meaning of our country, ＂clean＂ football league culture and raise the quality and level of fair competition have extremely good practical significance, possesses operability.
